Definitions

  • the present invention relates to a link chain as a conveyor chain for a cell conveyor, which consists of the chain and a plurality of this in series successively mounted conveyor cells existing, endless conveyor strand to (at least) arranged at the ends of the conveyor track deflection wheels, one of which is driven and the other acts as a tensioning wheel, in particular for a (chain) bucket elevator, in particular a single or double bucket elevator with (if appropriate in each case) central chain arranged centrally to the buckets, with a multiplicity of pairs with mutual (transverse) Distance parallel to each other and arranged parallel and mirror-symmetric to the chain longitudinal axis (flat iron) inner plates, each connected to form an (inner) chain link in the region of its end portions by two perpendicular to the chain longitudinal axis in a plane extending (chain) bolt are, which in each case by the two inner tab associated with them n of a (inner) pair of straps and two outer straps with i.w.
  • a cup) - with a support plate or the like. is to be connected, and wherein in each case between the two inner plates extending central bolt portion, a (chain) bolt, which comes when running the chain on the guide wheels with this under high load, has a larger diameter than the two in each case in the area a interviewedlasche lying Bolzenendabitese.
  • This average increase in diameter not only serves to reduce the surface pressure in the highly loaded contact areas (and a concomitant increase in the moment of resistance and thus the flexural rigidity), but at the same time to form two annular stops each bolt to which the respective inner straps applied during assembly from the outside can be.
  • a so-called “Elevator” designated (chain) bucket elevator meant, so one of the oldest continuous conveyor to the vertical (vertical bucket elevator), oblique (slanting) Bucket elevator) or horizontal (pendulum bucket elevator) conveying of bulk material, the conveyor cells (supporting members) are designed for the bulk material to be conveyed as so-called.
  • Mug the ia made of steel (welded or deep-drawn type), gray or cast aluminum, plastic or rubber, and - depending on the type of bulk material to be conveyed - different shapes (eg flat, flat, medium, deep with flat or curved rear wall) have can (see, for example, DIN 15231-15235, 15241-15245, 22201-22203, 22211-22213).
  • the largest spread is still likely to be the vertical bucket elevator (see, for example, VDI guideline 2324 "Vertical bucket elevator"), which, for example, is indispensable as a vertical continuous conveyor for cement clinker from modern cement plants.
  • central chain bucket elevators are generally designed as (single) bucket elevators with a cup strand, they can also be designed as so-called double bucket elevators.
  • two single-stranded central chains are housed with respective cup occupation in a common bucket elevator housing, and are each driven in common by a drive wheel (on a common shaft) of only one drive, while the tensioning wheels i.a. yes sit on separate waves, because the chain length of the two (central) chains can be different in size, so that independent clamping paths are highly appropriate in a double bucket elevator.
  • tension member (s) for bucket elevator find chains or straps (formerly ropes) use, with chains (and ropes) can be arranged single and double-stranded in single-stranded training as so-called.
  • Central chain centered to the cup back wall, and in two-stranded training in mirror-symmetrical Arrangement for center of the cup, either also on the cup back wall or on the side walls of the cup.
  • the endless traction elements are guided at the ends of the conveyor line, ie at the top and bottom of the bucket elevator, via rollers, wheels in the form of sprockets or profiled wheels or drums, where they are deflected, i.a. the drive on the head and the required bias of the tension member on the foot takes place.
  • the deflecting members are hereinafter - regardless of their specific training - generally referred to as “deflecting wheels” (or as “drive wheel” or “tensioning wheel”).
  • the bulk material to be conveyed is supplied to the cups by feeding devices, such as feed chutes or vibratory conveyors (task bucket), or it is scooped by the cups in the bucket elevator (from the so-called "sump") (Schöpf-bucket elevator).
  • Bucket elevators are preferably used for fine-grained bulk materials, since the pumping forces and thus the stresses of the tension member and the cup are very large in lumpy materials.
  • the emptying of the cup is either by gravity (slow-runner) or by centrifugal force (fast-runner), which in buckets with gravity discharge a free or controlled ejection is possible.
  • Chain bucket elevators have link or link chains as traction elements, wherein the link chains can be designed as round link chains (round steel chains) or web chains, which i.a. be used as hand or load chains in hoists use, while the known in various versions link chains esp. As transmission chains, as well as load chains, as well as conveyor chains for chain conveyor in question.
  • link chains The simplest (and cheapest) type of link chains are the stud chains. Their tabs rotate i.d.R. immediately on end (e.g., by rivets or cotter pins) against longitudinal displacement of the secured (chain) pin.
  • the bolt chains belong esp.
  • the present invention primarily relates to a link chain for a (chain) bucket elevator, and in turn especially to a single-strand bucket elevator with a central chain arranged centrally with respect to the buckets, but moreover quite generally to cell conveyor of the type described above, even if they are not referred to in the strict sense of the usual conveyor technology terminology as "bucket elevators".
  • Bucket elevators This is, for example, the case when the conveyor line of a cell conveyor runs horizontally, and the conveyor cells (even if they are cup-shaped) but not (as in a pendulum bucket elevator) pendulum attached to the tension member, but are firmly connected to this.
  • a "bucket elevator" it is always quite a cell conveyor meant.
  • Stud chains especially in training as Gallsche chains have been known by Leonardo da Vinci for more than 500 years. They consist in principle of alternately successive inner and outer chain links, each of which - as has already been described above - consist of a pair of inner plates or a pair of outer plates, which overlap the two adjacent inner plate pairs respectively and with these in the two overlapping sections in each case by a transverse to the chain longitudinally extending chain pins are hingedly connected, as this is, for example, from a bicycle chain ago her generally known.
  • a complete chain link - as defined above - consists of an inner chain link and an outer chain link.
  • the link chains also comprise bush chains and roller chains, the pins of which - as in the case of the Fleyer chain - have a constant diameter.
  • the bushing chains have in principle over the pin chains a higher wear resistance, since their inner plates are pressed on (inner) sockets, which are movably seated on the bolt firmly connected to the outer plates, whereby the surface pressure is significantly smaller.
  • Socket chains (see, e.g., DIN 8154 and 8164) are used i.a. designed and used for small divisions.
  • Socket chains have therefore far outstripped the chain of chains for conveyor chains of chain bucket elevators due to the aforementioned (in particular wear) properties, and not only earlier (ie until the 1970s / 1980s) Articulated chains were mainly used in slow-running bucket elevators with gravity drainage and almost exclusively link chains in training as Rundglieder- or round steel chains were used for fast runner with centrifugal emptying), but also after they have been due to the development in the meantime regularly for high-speed bucket elevators u.dgl. are preferably used.
  • roller chains are generally the most important because of their almost unlimited range of application, although they are the most expensive type of (steel) link chains. Their difference to the bush chains consists in particular in mounted on the bushes, hardened (and i.a. sanded) (Schon-) roles for wear and noise reduction.
  • articulated chains Since the outer flaps of link chains overlap their respective associated inner flaps at their end portions, and i.a. are arranged closely adjacent to the outer sides of the inner plates adjacent to them, and since the chain pins i.a. extend largely free of play with relatively narrow fit through the correspondingly formed tab through holes, have articulated chains compared to the all sides movable link chains only a small transverse mobility. Although articulated chains do not tolerate any significant diagonal pull in the transverse direction, they also provide a good (possibly central) guide against sideways migration, as is especially desirable or necessary for a chain bucket elevator with a central chain, since the chain is otherwise i.a. is guided only at the located at the ends of the conveyor track guide wheels (positive fit).
  • At least one of the deflection wheels of a chain bucket elevator is i.a. designed as a sprocket. It does not necessarily have to be the drive wheel on which the drive force is introduced into the chain (s) acting as the tension member (s), even if it assumes considerable values in a large cell conveyor.
  • belt bucket elevators for larger delivery heads and winningströme are for certain applications, in particular a hot goods transport, regularly not applicable (see eg Z " Cement, Lime, Gypsum ", 1974, H. 4, p. 176-181 ), so that the chain-driven cell conveyor, such as.
  • the Kettenbecherwerk still plays a significant role, and thus esp. Also its serving as a tension member and suspension means for the conveyor cells chain.
  • a lashing chain for bucket elevators in which the inner plates together with two chain pins form a prefabricated, frame-shaped assembly with which the jacks for attaching the link chain to cup side connecting webs provided outer plates are connected by a combined insertion and pivoting movement.
  • the inner plates are rotatably connected to the chain pins, and although the latter are preferably in holes the inner plates pressed.
  • the present invention has for its object to improve the above-described joint chain esp. To the effect that - despite the i.a. very rough operating conditions in their intended use as a conveyor chain for bucket elevators or the like. - i.w.
  • the considerable advantages of a bolt chain compared to a bush or roller chain esp. Very simple and cheap design), but still compared to conventional bolt chains significantly increased wear resistance (and thus a correspondingly high stability and durability), but much more reliable than a book chain, while still largely maintenance-free, with a large assembly and disassembly ease (without special tools) to further increase the life of a turning of the chain should also be possible.
  • the conveyor link chain according to the invention is clearly a new intermediate form between a conventional bolt chain and a chain, because on the one hand there are no inner bushes surrounding the central pin section, as they are generic for a bush chain, but on the other hand the pin bearing is not like a conventional pin chain takes place in the tabs (there possibly in pressed into the tab holes, cylindrical bearing shells), but in cup-shaped, firmly connected to the outer plates outer sockets, such as this of bushing chains partly is known per se, namely then (and only then), where it has been made use of "floating" bolt, which are freely rotatable and limited axially movable in each of two outer sockets and an inner bushing aligned to this inner, complete socket encapsulation ,
